I assume you have read the R Input/Output manual here: http://cran.r-project.org/doc/manuals/ The function read.csv is for reading comma-separated-values. Your data look to be tab-separated? Try using read.delim or read.table. Be sure to read the help page for ALL functions you try to use, even if you are following someone else's example. As an aside, when posting to the list, please include the output of sessionInfo() at least once in each email when you want help with something. It lets the rest of us know what version of R, what packages (and versions) you are using, language settings, etc. Sean > -- output of sessionInfo(): > > I tried doing the following : > > de=read.table(textConnection(" > ID_REF GSM133971 > GSM133972 GSM133973 > + 244901_at 5.95461158752441E+001 1.88836498260498E+001 > 1.98215045928955E+001 > + 244902_at 7.25400314331055E+001 2.65250205993652E+001 > 1.95321922302246E+001 > + 244903_at 2.23291015625000E+002 1.78133636474609E+002 > 5.38166885375977E+001 > + 244904_at 3.65505447387695E+001 3.04016351699829E+000 > 6.80462265014648E+000 > + 244905_at 4.07523269653320E+001 2.58869285583496E+001 > 1.18088026046753E+001 > + 244906_at 1.50184860229492E+002 5.39840278625488E+001 > 4.14917945861816E+001 > + 244907_at 2.65190029144287E+001 1.39808797836304E+000 > 2.08662915229797E+000 > + 244908_at 3.50156021118164E+000 1.05003893375397E+000 > 4.57657009363174E-001 > + 244909_at 1.02663551330566E+002 1.42618169784546E+001 > 1.61735534667969E+001 > + 244910_s_at 7.20161895751953E+001 1.57578134536743E+001 > 1.31729679107666E+001 > + 244911_at 3.26349411010742E+001 7.23858451843262E+000 > 6.47778940200806E+000"),header = TRUE,as.is= TRUE,sep = ',') > > > str(de) > 'data.frame': 11 obs. of 1 variable: > $ ID_REF...........GSM133971..........GSM133972...............GSM133973: > chr "244901_at 5.95461158752441E+001 1.88836498260498E+001 > 1.98215045928955E+001" "244902_at 7.25400314331055E+001 > 2.65250205993652E+001 1.95321922302246E+001" "244903_at > 2.23291015625000E+002 1.78133636474609E+002 5.38166885375977E+001" > "244904_at 3.65505447387695E+001 3.04016351699829E+000 > 6.80462265014648E+000" ... > > > > But when I try doing for the whole dataset I get an error: > > de=read.table(textConnection("trans.csv"),header = TRUE,as.is= TRUE,sep = > ',') > > de > > [1] trans.csv > <0 rows> (or 0-length row.names) > > -- > Sent via the guest posting facility at bioconductor.org. > > _______________________________________________ > Bioconductor mailing list > Bioconductor@r-project.org > https://stat.ethz.ch/mailman/listinfo/bioconductor > Search the archives: > http://news.gmane.org/gmane.science.biology.informatics.conductor > [[alternative HTML version deleted]]
